Got the truck from a family friend, she was sick of working on it,new motor, heads and countless other parts. won't start when hot most of the time, sluggish, acts like clogged fuel filter, but it's new. i replaced the icm and tps, still has a tps code, has a hesitation like it is missing or out of timming. I looked and it has a new temp. sending unit as well, i just need to know the right way to adjust tps or if it sounds like somthing else.

You might have a bad ground. According to my Haynes manual's wiring diagram, both gauges share the same ground and typically that is "located on the left side of the instrument panel", wherever that is. Sorry I can't be more specific about the location. While it may not be true on your vehicle (the wiring diagram states "typical late model" in its description), my wiring diagram says that the ground wire is Brown (BR). You might try locating that wire and track it to its attachment point. You also might try tapping into it and using a continuity tester and ground out the wire to metal (there's plenty of grounding points under there). Make sure the ignition key is off!! There might be a bad ground wire closer to the meters than the attachment point. Hope this is helpful. Allow plenty of time if you're going to investigate this yourself. Do you have other gauges? Do they work? I think that all of the gauges are ganged through the same fuse (but not through the same ground wire). You might consider checking the fuse to ensure that it's OK. Your owners manual that came with the truck will tell you which fuse is it. If there are other things on the same fuse and they work, it's not the fuse. I hope that this is helpful.

If you have a tps and air flow meter you have a 22re fuel injection.
Check for codes by jumping TE1 and E1 or jumping diagnosis connector.
The 22re will run with out the tps(throttle position sensor) plugged in. But it will not run with the air flow meter unplugged. The air flow meter controls the fuel pumps voltage.

This page tell you how to test those sensors. Then we can go from there.
The fuel pressure regulator may be shot also, but we will see.
I hope this was helpful.

Try changing out your turn signal flasher.it might be under your dash by your fuse box.Some trucks have two one for turn signals one for 4 way flashers.By all means check the fuse first.
